Ultrasonic wave transmission medium supply/discharge member and endoscope system

Abstract

An ultrasonic wave transmission medium supply/discharge member includes a balloon for an ultrasonic endoscope that is mounted to cover an outer surface of an ultrasound transducer provided in a distal end part body on a distal end side of an insertion portion of an ultrasonic endoscope, in which the balloon for an ultrasonic endoscope has a storage portion that is configured to be filled with an ultrasonic wave transmission medium, a tube that communicates with an inside of the storage portion, and a fixing portion that is configured to be attachably and detachably fixed to an operating portion of the ultrasonic endoscope and that is connected to the balloon for an ultrasonic endoscope through the tube.

         2 . The ultrasonic wave transmission medium supply/discharge member according to  claim 1 ,
 wherein the fixing portion has an operation member that operates to hold and release a fixed state of the fixing portion to the operating portion.   
     
     
         3 . The ultrasonic wave transmission medium supply/discharge member according to  claim 1 ,
 wherein the fixing portion has a port portion that supplies and discharges the ultrasonic wave transmission medium into and from the tube.   
     
     
         4 . The ultrasonic wave transmission medium supply/discharge member according to  claim 3 ,
 wherein the port portion has a supply/discharge port to which a supply/discharge unit for supplying and discharging the ultrasonic wave transmission medium is connectable.   
     
     
         5 . The ultrasonic wave transmission medium supply/discharge member according to  claim 4 ,
 wherein the supply/discharge port has a shape that is connectable with a luer lock connector.   
     
     
         6 . The ultrasonic wave transmission medium supply/discharge member according to  claim 4 ,
 wherein the supply/discharge port is configured to supply and discharge the ultrasonic wave transmission medium through a luer lock connector.   
     
     
         7 . The ultrasonic wave transmission medium supply/discharge member according to  claim 1 ,
 wherein the fixing portion has
 a pair of grip bodies facing each other, and 
 a connecting member that rotatably connects the pair of grip bodies to each other. 
   
     
     
         8 . The ultrasonic wave transmission medium supply/discharge member according to  claim 7 ,
 wherein the connecting member has a port portion that supplies and discharges the ultrasonic wave transmission medium into and from the tube.   
     
     
         9 . The ultrasonic wave transmission medium supply/discharge member according to  claim 8 ,
 wherein the port portion has a structure that is attachable to and detachable from the connecting member.   
     
     
         10 . The ultrasonic wave transmission medium supply/discharge member according to  claim 7 ,
 wherein the fixing portion has a grip force applying member that applies grip force of the pair of grip bodies.   
     
     
         11 . The ultrasonic wave transmission medium supply/discharge member according to  claim 1 ,
 wherein the fixing portion has a shape that avoids a protrusion portion included in the operating portion.   
     
     
         12 . The ultrasonic wave transmission medium supply/discharge member according to  claim 11 ,
 wherein the fixing portion has a shape that is engageable with a shape of the protrusion portion.   
     
     
         13 . The ultrasonic wave transmission medium supply/discharge member according to  claim 11 ,
 wherein the protrusion portion is a forceps introduction portion of a forceps sleeve provided in the operating portion.   
     
     
         14 . The ultrasonic wave transmission medium supply/discharge member according to  claim 1 ,
 wherein the fixing portion has an anti-slip member at a portion that comes into contact with the operating portion.   
     
     
         15 . An endoscope system comprising:
 the ultrasonic wave transmission medium supply/discharge member according to  claim 1 ; and   an ultrasonic endoscope including an operating portion that is configured to be attachably and detachably fixed to the fixing portion.   
     
     
         16 . The endoscope system according to  claim 15 ,
 wherein the operating portion has a protrusion portion that is engageable with the fixing portion.   
     
     
         17 . The endoscope system according to  claim 16 ,
 wherein the protrusion portion is a forceps introduction portion of a forceps sleeve provided in the operating portion.
